  1. Facilities Management and Design Chapter 5 Water and Wastewater systems

  2. Water usage levels and patterns • Water consumption levels vary • Type of hotel • Location • Facilities • Managerial attention to water usage • Larger properties use more water per room than smaller • As the level of services increases, so does water consumption • On-site laundry • Kitchens • Irrigation • Cooling towers

  3. Deduct meters—no disposal charges on cooling towers, irrigation, swimming pool Subsystems and isolation devices Fire systems Potable systems Hot/ Cold Equipment/ Human use Backflow preventers Building water system pipes galvanized iron Steel Copper Plastic (PVC, CPVC) Contain water under pressure The basic structure of water systems

  4. Storm sewer system (rainwater) Sanitary sewer system (removal of waste products) Grease separator or grease trap Facility owned sewage systems septic tanks treatment plants Plumbing risers sewer gas traps Vents Pipe insulation (to prevent heat loss, condensation) The basic structure of wastewater systems

  5. Potability Bacteria Nitrates Trace metals Organic chemicals Aesthetics Color Odor Taste Clearness Mineral content Acidity/alkalinity Legionnaires' Disease bacterial growth in cooling towers Water quality problems

  6. Water heating • Heating cost exceeds water cost • Safety equipment - proper installation (mixing valves) • Separate water heaters/boosters for kitchen needs • Dedicated water heating systems for laundry operations

  7. Water heating options • Traditional options • directly fired water heaters • indirectly fired water heaters • Non-traditional options • heat pump water heaters • waste heat recovery • solar energy

  8. Water system maintenance issues • Treating water to make it appropriate to the application need • replacing sacrificial anodes • cleaning filters and strainers • lubricating pumps • checking hot water temperature settings • checking pressure relief valves • repair of leaking valves • general caulking, sealing • water heater inspections • wastewater system clearing • inspecting and cleaning gutters, roof drains, site drainage

  9. Water for entertainment and recreational purposes • Landscaping elements • Fountains • Ponds/ Lakes • Streams • Recreation • Swimming pools • Slides

  10. Pool maintenance • Involves cleaning the pool, equipment, and water • Skimming • Vacuuming • Brushing • Lime buildup removal • Equipment pumps, filters • Water pH level 7.2 to 7.6 • Chlorine and algicide control algae • Pool heating

  11. Water conservation • encouraged by rising costs, decreasing availability, and government restrictions on water usage • Conservation strategies • low-flow shower heads (check guest reaction) • re-use of water (gray water) • careful control of landscape irrigation • foot-operated faucets in kitchens • keeping up with basic maintenance on water systems
